Improvement in car-couplings



UNITED STATES PATENT OFFICE.,

JOSEPH WILOOX, OF CANTON, PENNSYLVANIA.

IMPROVEMENT IN CAR-COUPUNGS.

Specication forming part of Letters Patent No. 141,846, dated August12,1873; application filed February 28, 1873.

To all whom it may concern:

Be it known that I, JOSEPH WILoox, of Canton, in the county of Bradfordand State of Pennsylvania, have invented certain new and usefulImprovements in Cary-Coupling, and I do hereby declare that thefollowing is a full1 clear, and exact description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangementof a ear-coupling, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a side elevation of my car-coupling, showing one of thedraw-heads in longitudinal vertical section. Fig. 2 is a horizontalsection of one of the draw-heads.

My car-coupling is simple 5 and consists merely in the application ofthree springs and a tube to an ordinary draw-head, with the usual pinand link, and can readily be attached to any draw-head now in use, theobject being to make the same self-coupling, and to hold the link inproper position fbrcoupling.

A A represent two draw-hads of any of the known and usual forms. B B arethe coupling-pins, and O is the coupling-link. In each draw-head A aretwo springs, D D, fastened one to each side of the mouth or entrance ofthe draw-head, and extending toward the rear. The front portions of thesprings D D are slightly curved, as shown in Fig. 2, while the rearportions are straight; and along the upper edge of each of said straightparts is an inward-projecting flange, a. In the top of the mouth of thedraw-head is fastened another spring, E, which extends inward anddownward, as shown more particularly in Figpresses the inner ends of thesprings D Dv apart, till the flanges a a become so far separated thatthe pin B will fall down of its own weight and couple. The spring Eholds the link O in a horizontal position, so that it will enter theopposite draw-head without being guided, as usual, by hand, thus doingaway with one of the most fruitful sources of accidents in couplingcars.

Having thus fully described my invention, i.

what I claim as new, and desire to secure by Letters fatent, is-

-The spring E, attached to the front part of the draw-head, extending-backward andwresting upon the link O, in combination with the springs DD, having anges a a, and pin B, all constructed and arranged foroperation as set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

JOSEPH WILCOX.
